Please modify your program so that x become of "mp" type.

In general, there is no interconnection between "sym" and "mp" - since "sym" is of closed format of Mathworks.
We are not able to provide mixed-type operations for them.

Thanks for reply. But x is variable in the function, I try to use mp(x), it didn't work.

There is only one way of converting 'sym' to 'mp' - through the string:

x = mp(char(x)) % x becomes of mp type
